Windows 10 Media Creation Tool Error: 0x80042405 - 0xA001A

Greetings,

Recently, I have seen many people inquiring about this error regarding the Media Creation Tool. I myself got this error when I try to create a bootable USB drive (aka Create an Installable Media).

Here's what I tried:

Reformatting USB drive to FAT32

Deleting files

Tried to locate and run Setupprep.exe (I couldn't find this file in C:\$Windows.~BT\Sources or anywhere)

Change Startup Type of Update-Related Services (Startup Type: Manual -> Automatic)

Uninstalled and Reinstall Windows 10 Media Creation Tool

Made sure my USB is above 8Gb as instructed by the tool (it is 15Gb)

The Fix (for me at least):

1. Downloadthe Windows 10 Media Creation Tool directlyinto the USB drive that you want to use as a bootable device (meaning you download the Tool into the same USB you chose to use as an Installation Media). If you already downloaded the tool on your PC's Desktop, copy it into your USB.

2. Run the Tool directly from your USB, meaning you open File Explorer, locate the MediaCreationTool.exe in your USB and double-click to run it.

The installer should then create an Installation Media/Bootable USB.

Hope this helps!

Cheers,

Tom

    No, didn't work. I should really learn that when a product is non-refundable it means it's fundamentally broken, and the seller is nothing more than a scam artist.

    Attempting this fix right now, thanks to Tom for writing about it.

    It occurs to me that this has now been an issue for over 1 year, and Microsoft still fails to mention it in their step-by-step guide on the 'Download Windows 10' page. It's your main product, Microsoft, maybe try sorting it out, if only from a PR point of view.

    When I tried to create a new USB bootable drive by Windows 10 Media Creation Tool for the first time, no problem appeared. USB had been created. When I tried to create this same USB again, the metioned error occured. I tried it again and again, but no success. Alwys formatted the USB drive. I realized that for the first time I have named the partition before formatting the USB. Another creations without naming the partition. For the last time I tried to format USB again and name the partition - success. Maybe it helps.
